According to the command documentation git branch, to flag -M assumes the role of --move together with --force.

This means that when executing the command, the branch will be renamed to main, even though this branch already exists (effect caused by --force).

Therefore:

git branch -M main

Is the same as:

git branch --force --move main

If the name of branch before executing the command is, for example, master, after his execution, shall main.
